Answer:
d. the travel time
Step-by-step explanation:
We are studying the travel time for the college student, which is between 40 and 90 minutes, distributed uniformly.
40 and 90 minutes are the intervals of the variable, and the variable is the travel time, which is random. Uniform is how the distribution is characterized, which means that each outcome(travel time beween 40 and 90 minutes) is equally as likely.
So the correct answer is:
d. the travel time

Answer:
Kindly check explanation
Step-by-step explanation:
The hypothesis :
H0 : μ = 3000
H0 : μ ≠ 3000
The test statistic :
(xbar - μ) ÷ (s/√(n))
xbar = 3500
μ = 3000
σ = 300
n = 30
(3500 - 3000) ÷ (350/√(30))
Test statistic = 7.824
Df = 30 - 1 = 29
Tcritical at 0.01 = 2.462
Test statistic > critical value ; we reject H0 ; and concluded that there is significant evidence that
μ ≠ 3000
The answer is 8.4km/hr
(6+6+6+12+12)÷5=8.4
I don't know how to explain it it's as easy as 2+2 but as hard as explaining how to get 4 from 2+2
